Equipment
- Large skillet
- 9x13 inch baking dish
- Large bowl
- Whisk
- Spatula
Ingredients
Main Ingredients
- 1 pound Pork sausage or bacon, ham, or your favorite breakfast meat
- 6-8 slices Bread day-old (French bread, sourdough, or whole wheat recommended)
- 2 cups Shredded cheddar cheese or a blend like Monterey Jack or Colby
- 8 Large eggs
- 1.5 cups Milk whole milk or 2%
- 0.5 teaspoon Salt
- 0.25 teaspoon Black pepper
Optional Add-ins
- 0.5 cup Diced bell peppers
- 0.5 cup Diced onions
- 0.5 cup Mushrooms
- 1 cup Spinach
Instructions
Preparation
- Cook the sausage in a skillet until browned, then drain and set aside.
- Tear bread into 1-inch cubes and spread evenly in a greased 9x13 inch baking dish.
- Layer the cooked sausage and any optional vegetables over the bread cubes.
- Sprinkle two-thirds of the shredded cheese over the meat and bread layer.
Assemble & Bake
- Whisk eggs, milk, salt, and pepper together in a large bowl until well combined.
- Pour the egg mixture over the casserole ingredients, pressing down on the bread to ensure it soaks up the liquid.
- Cover and refrigerate for at least 30 minutes, or preferably overnight.
- Preheat oven to 375°F (190°C), then uncover the casserole and sprinkle with the remaining cheese.
- Bake for 45-55 minutes until golden brown and set, then let rest for 5-10 minutes before serving.
Notes
For best results, prepare the casserole the night before and let it chill overnight. This allows the bread to fully absorb the egg mixture, resulting in a more tender and flavorful casserole.
